MAME ROMs not launching

hello,
just got Lutris installed in POP!_OS (Ubuntu 18.10).
i am running Steam games fine, awsome.
however I tried downloading Arcade games from the lutris website and am experiencing difficulties running them.

example:
Bubble Bobble
when i clicked install it downloaded the Arcade (MAME) runner, and now I see that in Lutris.
I then chose ~/Games/bubble_bobble as the game folder
I downloaded the ROM and chose bublboblr.zip as the ROM file.
when I attempt to launch the game I get a flash on the screen then nothing.
the log shows:
